Xfinity internet dropping

Yes, I have reviewed the troubleshooting steps but in all honesty I think I need some advice specific to my issue. I have reset my system over and over again, but still get frequent connection drops. This is most noticeable with online gaming, where I will be booted frequently due to loss of internet connection. This drop generally only lasts a few seconds, but it's enough to interrupt what I am doing. 

My setup is an Arris Surfboard in bridge mode, which bridges to a google nest setup (the Arris bridges to a nest router, which itself runs both the ethernet connection to a splitter which allows for a wired connection to about 3 devices, and connects to 2 other google nest wifi points throughout the house to create a wifi mesh). I cannot find any obvious problems with the set-up to explain these issues (which quite frankly occurred even before my current set-up, using the default Comcast modem/router set-up). 

I did try to check the event logs on the Arris but it seems that I am unable to do this, perhaps because it is in bridge mode? I could share event logs from my PC, which has a wired ethernet connection, but I am unsure of what to look for in these logs to demonstrate the issue.

Thanks, 

u/user_287yt4 when it comes to third party gear our amount of support is limited. We can only do basic troubleshooting such as what you have already done, then we would set up an appointment for a tech to come provide hands on help. These appointments can be a fee of $100.00. 

As I said above, these issues occured even with the gear provided by Comcast, so I'm not going to pay $100 for a tech to come and blame it on my set-up. Quite frankly I would cancel my Xfinity subscription if it was not the only option in my area. I plan to do so as soon as another option becomes available.

Thank you for sharing your concerns, user_287yt4. We do not charge for visits if the root cause is Xfinity owned equipment or wiring. We charge for visits if the root cause is customer owned equipment, customer owned wiring, or education. Part of the troubleshooting steps that we do to try and prevent a charge from happening such as having you reach out to the modem manufacturer to ensure there are no issues on their end.  

Do you have any splitters between the coax wall outlet and the modem? Have you tried replacing the coax cable between the wall outlet and the modem?
